Abstract

Excess nutrients can cause surface waters to be in violation of water quality criteria. Therefore, a tool is needed to enhance the understanding of the extent to which water reuse practices contribute to nutrient impairments. This project will assess the contribution of water reuse practices to nutrient impairments by using a marker-based tool, iohexol. This project will demonstrate the applicability of iohexol to serve as a universal marker for water reuse effluent, validate a previously developed marker-based approach using iohexol, and develop a guidance manual to assist water utilities in determining the nutrient loading from water reuse practices.

Originally funded as WERF project WRF1727.
